Description

Technical Field

[0001] This utility model relates to the field of geotechnical engineering investigation technology, and in particular to a borehole water level measuring device for geotechnical engineering investigation. Background Technology

[0002] In geological exploration, drilling equipment is used to drill a small-diameter, deep cylindrical hole into the ground, also known as a well. Water level refers to the elevation of the free water surface of a water body above a fixed base surface, and its unit is meters. Borehole water level measurement is to measure the water level inside the borehole to provide data for subsequent engineering.

[0003] A search revealed a public disclosure (announcement) number: CN214330608U, which discloses a borehole water level measuring device based on geotechnical engineering investigation. This device, belonging to the field of geotechnical engineering investigation, includes a base plate. A fixing frame is fixedly connected to the upper surface of the base plate. An mounting plate is positioned below the fixing frame, with both ends of the mounting plate fixedly connected to the inner walls of the two sides of the fixing frame. A first groove is formed on one side of the mounting plate, and a round rod is placed inside the first groove. A first through groove is formed in the middle of one end of the round rod. This invention improves the accuracy of water level measurement by incorporating a round rod inside the mounting plate, with a measuring wire wound around its outer side. The measuring wire is fixedly connected to a movable block. Two measuring leads from a measuring ammeter pass through a winding wheel and are fixedly connected to two metal conductive strips at the bottom of the movable block. By rotating a handle, the measuring wire and the movable block move downwards until the two movable blocks contact the water surface, forming a circuit. This causes a change in the ammeter reading.

[0004] Although the above scheme forms a circuit by contacting the movable block with the water surface, thereby changing the ammeter reading and improving the accuracy of water level measurement, if the debris and sediment attached to the measuring line in the borehole are not removed in time, measurement errors will occur in the next measurement due to the accumulation of dirt. Therefore, we propose a water level measuring device for boreholes in geotechnical engineering exploration. Utility Model Content

[0005] The main purpose of this utility model is to provide a borehole water level measuring device for geotechnical engineering exploration. By setting up a line laying unit and a cleaning unit, it solves the problem that if the debris and sediment attached to the measuring line in the borehole are not removed in time, measurement errors will occur in the next measurement due to the accumulation of dirt.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A borehole water level measuring device for geotechnical engineering exploration includes a main unit, a line-laying unit and a cleaning unit disposed inside the main unit, and a measuring unit disposed above the main unit, wherein the cleaning unit is located on the side of the line-laying unit.

[0008] The wire feeding unit includes a U-shaped seat installed on the top of the main unit, a rotating shaft movably installed inside the U-shaped seat, a measuring guide block set below the main unit, a suspension wire wound around the side wall of the rotating shaft and fixedly connected to the measuring guide block, and a retracting handle installed at the input end of the rotating shaft.

[0009] The cleaning unit includes a fixing groove on the top of the main unit, a receiving groove on the side wall of the fixing groove, a threaded shaft movably disposed inside the receiving groove and having threads with opposite directions at both ends, a movable part installed on the circumferential side of the threaded shaft, a clamping part installed on the side wall of the movable part, and an adjusting part disposed at the end of the threaded shaft.

[0010] Preferably, the main body unit includes a gantry base, a connecting seat mounted on the side wall of the gantry base, and a movable wheel mounted on the bottom of the connecting seat.

[0011] Preferably, the main body unit further includes a threaded through hole opened on the top of the connecting seat, and a threaded rod that is movably inserted through and disposed in the threaded through hole.

[0012] Preferably, the adjusting component includes a rotating disk mounted on the input end of the threaded shaft and an adjusting handle mounted on the side wall of the rotating disk.

[0013] Preferably, the clamping member includes an L-shaped connecting rod mounted on the side wall of the moving member, and an arc-shaped clamping plate mounted on the end of the L-shaped connecting rod.

[0014] Preferably, the cleaning unit further includes a limiting washer installed on the side wall of the receiving groove, and the limiting washer is sleeved on the circumferential side of the threaded shaft.

[0015] Preferably, the measuring unit includes a fixed base mounted on the top of the gantry, a measuring ammeter mounted on the fixed base, a U-shaped base mounted on the inner side wall of the fixed base, a rotating column movably mounted in the U-shaped base, and a measuring wire with one end fixedly connected to the measuring ammeter and the other end fixedly connected to the measuring guide block and wound around the surface of the rotating shaft.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In this invention, through the included wire-laying and cleaning units, when water level measurement is required, the measuring device is pushed above the borehole, and the retracting handle is rotated. This causes the suspension wire to move down along the measuring guide block until the metal conductive strip inside the measuring guide block contacts the water surface, forming a circuit. This causes a change in the current reading on the measuring ammeter. Then, the retracting handle is stopped, and the value of the suspended wire is recorded, allowing for easy and accurate reading of the water level, facilitating the measurement of borehole water levels. When it is necessary to retract the measuring wire after measurement, the device can be easily cleaned. During winding, turn the adjustment handle to make the rotating disk drive the threaded shaft to rotate. Since there are two sections of threads with opposite directions on the threaded shaft, the two moving parts can drive the clamping parts to move closer to each other along the threaded shaft until the arc-shaped clamping plates are in contact with the side wall of the measuring line. Then, rotate the release handle counterclockwise to make the measuring line continuously move upward and wind around the side of the rotating shaft. The arc-shaped clamping plates remove the debris and deposits attached to the measuring line in the borehole, avoiding measurement errors caused by dirt accumulation and ensuring the accuracy of subsequent measurements.

The retractable handle 204 facilitates the rotation of the rotating shaft 202.

[0031] like Figure 4 As shown, the cleaning unit 3 includes a fixing groove on the top of the main unit 1, a receiving groove on the side wall of the fixing groove, a threaded shaft 301 movably disposed inside the receiving groove and having threads with opposite directions at both ends, a moving part 303 mounted on the circumferential side of the threaded shaft 301, a clamping part 304 mounted on the side wall of the moving part 303, and an adjusting part 302 disposed at the end of the threaded shaft 301. When the adjusting part 302 drives the threaded shaft 301 to rotate, the moving part 303 can drive the clamping part 304 to move along the threaded shaft 301.

[0032] like Figure 1 As shown, the main unit 1 includes a gantry 101, a connecting seat 102 installed on the side wall of the gantry 101, and a moving wheel 103 installed at the bottom of the connecting seat 102. The moving wheel 103 facilitates the convenient movement of the entire measuring device.

[0033] like Figure 3As shown, the main unit 1 also includes a threaded through hole opened on the top of the connecting seat 102, and a threaded rod 104 that is movably inserted through and disposed in the threaded through hole. Rotating the threaded rod 104 so that the bottom end of the threaded rod 104 extends below the ground can ensure the stable installation of the measuring device.

[0034] like Figure 2 As shown, the adjusting component 302 includes a rotating disk 3021 installed at the input end of the threaded shaft 301, and an adjusting handle 3022 installed on the side wall of the rotating disk 3021.

[0036] like Figure 3 As shown, the measuring unit 4 includes a fixed base mounted on the top of the gantry 101, a measuring ammeter 401 mounted on the fixed base, a U-shaped base 402 mounted on the inner side wall of the fixed base, a rotating column 403 movably mounted in the U-shaped base 402, and a measuring wire 404 with one end fixedly connected to the measuring ammeter 401 and the other end fixedly connected to the measuring guide block 205 and wound around the surface of the rotating shaft 202. The measuring wire 404 enables the conductive connection between the measuring ammeter 401 and the measuring guide block 205.

[0037] When water level measurement is required, push the measuring device above the borehole, rotate the retractable handle 204, causing the suspension line 203 to move the measuring guide block 205 down until the metal conductive strip inside the measuring guide block 205 contacts the water surface, forming a circuit. This causes a change in the current index on the measuring ammeter 401. Then stop rotating the retractable handle 204 and record the value of the measuring suspension line 203 at this time. This allows for easy reading of the accurate water level value, facilitating the measurement of the borehole water level by the staff. Example

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, a borehole water level measuring device for geotechnical engineering exploration includes a main unit 1, a line-laying unit 2 and a cleaning unit 3 disposed inside the main unit 1, and a measuring unit 4 disposed above the main unit 1, wherein the cleaning unit 3 is located on the side of the line-laying unit 2.

[0039] like Figure 5 As shown, the wire feeding unit 2 includes a U-shaped seat 201 installed on the top of the main body unit 1, a rotating shaft 202 movably installed inside the U-shaped seat 201, a measuring guide block 205 set below the main body unit 1, a suspension wire 203 wound around the side wall of the rotating shaft 202 and fixedly connected to the measuring guide block 205, and a retractable handle 204 installed at the input end of the rotating shaft 202. The retractable handle 204 facilitates the rotation of the rotating shaft 202.

[0040] like Figure 4 As shown, the cleaning unit 3 includes a fixing groove on the top of the main unit 1, a receiving groove on the side wall of the fixing groove, a threaded shaft 301 movably disposed inside the receiving groove and having threads with opposite directions at both ends, a moving part 303 mounted on the circumferential side of the threaded shaft 301, a clamping part 304 mounted on the side wall of the moving part 303, and an adjusting part 302 disposed at the end of the threaded shaft 301. When the adjusting part 302 drives the threaded shaft 301 to rotate, the moving part 303 can drive the clamping part 304 to move along the threaded shaft 301.

[0041] like Figure 1 As shown, the main unit 1 includes a gantry 101, a connecting seat 102 installed on the side wall of the gantry 101, and a moving wheel 103 installed at the bottom of the connecting seat 102. The moving wheel 103 facilitates the convenient movement of the entire measuring device.

[0042] like Figure 3 As shown, the main unit 1 also includes a threaded through hole opened on the top of the connecting seat 102, and a threaded rod 104 that is movably inserted through and disposed in the threaded through hole. Rotating the threaded rod 104 so that the bottom end of the threaded rod 104 extends below the ground can ensure the stable installation of the measuring device.

[0043] like Figure 2 As shown, the adjusting component 302 includes a rotating disk 3021 installed at the input end of the threaded shaft 301, and an adjusting handle 3022 installed on the side wall of the rotating disk 3021.

[0045] like Figure 4As shown, the cleaning unit 3 also includes a limiting washer 305 installed on the side wall of the receiving groove, and the limiting washer 305 is sleeved on the circumferential side of the threaded shaft 301. The setting of the limiting washer 305 avoids the moving part 303 from contacting and colliding with the side wall of the receiving groove during the movement of the threaded shaft 301.

[0046] like Figure 3 As shown, the measuring unit 4 includes a fixed base mounted on the top of the gantry 101, a measuring ammeter 401 mounted on the fixed base, a U-shaped base 402 mounted on the inner side wall of the fixed base, a rotating column 403 movably mounted in the U-shaped base 402, and a measuring wire 404 with one end fixedly connected to the measuring ammeter 401 and the other end fixedly connected to the measuring guide block 205 and wound around the surface of the rotating shaft 202. The measuring wire 404 enables the conductive connection between the measuring ammeter 401 and the measuring guide block 205.

[0047] When it is necessary to wind up the measuring line after the measurement is completed, rotate the adjusting handle 3022, so that the rotating disk 3021 drives the threaded shaft 301 to rotate. Since the threaded shaft 301 has two sections of threads with opposite directions, the two moving parts 303 can drive the clamping parts 304 to move along the threaded shaft 301 in a direction that is closer to each other, until the arc-shaped clamping plate 3042 contacts the side wall of the measuring line and stops. Then, rotate the retracting handle 204 counterclockwise, so that the measuring line suspension 203 moves up continuously and winds around the circumference of the rotating shaft 202. The arc-shaped clamping plate 3042 removes the debris and deposits attached to the measuring line in the borehole, avoiding measurement errors caused by dirt accumulation and ensuring the accuracy of subsequent measurements.
